Jackson is a big, workhorse ball carrier who has been a productive downhill runner his whole career in St Louis. He can wear defenses down with his powerful running style yet has enough quickness and agility to make people miss once he gets to the second level. He does a good job of running behind his pads and shows excellent balance on contact as well as the power to move piles near the goal line. He may lack the elite speed to take it all the way but still has enough top-end speed to produce the occasional 40- to 50-yard run.
